Features of the Trane Digital Thermostat
AUTO CHANGEOVER--When the system mode is set to Auto, the control automatically switches between heating and cooling modes to maintain the desired comfort level.
SETPOINT DEADBAND--The number of degrees separating Heating and Cooling setpoints. The amount of separation between mode setpoints is user defined between 2 and 10 degrees. When the control is set to Auto, and the cooling setpoint is changed to a cooler setting, the heating setpoint also changes to maintain the selected degrees separation. The same action occurs when the heating setpoint is changed to a warmer temperature.
BACKLIT DISPLAY & KEYS--The liquid crystal display and keypad will illuminate whenever a keypad button is pressed to improve control visibility. The back light stays on for 10 seconds after the last key press. The Up and Down arrows are continuously lit.
COOLING DROOP--Cooling Droop is an automatic function that cycles the compressor on to improve indoor comfort by removing moisture from the air. The Droop cycle is activated when space temperature is at or below the cooling sensible temperature setpoint. When this function is active, the control will control indoor temperature at 1 or 2 degrees below cooling setpoint. The Droop cycle is deactivated when the indoor temperature rises above the cooling setpoint.
KEYPAD LOCK--Locking the control keypad can help prevent unwanted tampering or changing the control settings by pressing the controls UP and DOWN arrow keypad buttons at the same time and holding for 2 seconds.

The Energy Savings mode hese keys is activated by pressing the Energy Savings key "$" on the control keypad. Pressing the Energy Savings key "$" again deactivates the Energy Savings mode. Pressing and holding the Energy Savings key "$" provides quick access to the offset degree setup for the current operating mode.

SERVICE INDICATOR--"SERVICE" automatically flashes when an internal fault or error has been detected by the control.
WAIT INDICATOR--"WAITING" will illuminate when the indoor setpoint is moved in the direction of calling for additional system capacity. "WAITING" indicates the control is adjusting to the new settings.
CALIBRATE INDOOR TEMPERATURE--This option allows calibration (or deliberate miscalibration) of the room temperature sensor. The selection is the number of degrees added to actual temperature. The number can range between +5 and -5. Factory default is 0. This adjusted value will be used as actual temperature for both display and hese keys control action. For example, if 2 is selected, 72 degrees actually will read 74 degrees.
